.ble therewithin fits therewithin and constitutes the generatingchamber, forming at the same time a sealing chamber for the bellslidably mounted upon the upper end of the generating chamber.

A still further object-of the invention is the provision of means forpreventing the carbid from interfering with the closure of the valve, sothat should the valve be held slightly open by the carbid between it andthe outlet of the hopper, the amount of carbid passing through suchoutlet will be retained by an auxiliary means which constitutes withsuch carbid a closurefor the outlet of the hopper and thus prevents thecontinuous flow of the smaller carbid into the generating chamber whenthe valve is not fully seated. 7

With the foregoing and other objects in view which" will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed canbe made within'the scopeof what is claimed Without I a by the carbid falling into the waterwithin the member 1, will cause. the bell 12 to eledeparting from thespirit of the invention. In the drawingsFigur.e 1 is a vertical centralsectional view through the complete generator. Fig. 2 is a sideelevation of the generating chamber showing the conduits led therefromand also the condensation receiving and directing pipes. Fig. 3 is a topplan view of the gas washing device. Fig. a is a section taken on lineof Fig. 3. Figs. 5 and. 6 are enlarged detail sectional views of thevalve and auxiliary valves of the carbid hopper. 'Fi'gz. 7 is anenlarged detail view illustrating a reserve carbid holder and the meansfor emptying the same. i

Referring to the drawings, B designates the base, which is preferablymade of metal and hasresting thereupon the frusto-conical generator 1,which with the outer cylindrical casing 2, which is connected to thebase to form a water tight joint, forms the concentric sealing chamber 3and as the member 1 is provided with the openings 1' at the bottomthereof, the water admitted into the sealing chamber will also fill thegenerating member 1 approximately to the line 4 as illustrated inFig. 1. By this means, it will be seen that the water that is used forseallng the bell 12 also fills the generator member 1 for the generationof the acetylene gas.

Removably mounted upon the upper end or rim of the member 1, is the gaswashing member 5, which is made in the form of a hollow ring, the samebeing provided with the inlet or filling spout 6 to the gas washmgchamber 7. A gas inlet pipe 8 is carried by the member 5 and opens at apoint above the water within the chamber 7 below the deflector 9, whichis so disposed as to cause the gas to pass downwardly into the water inthe direction of the arrows, as

member 5 and telescopically fitting upon the upper end of the pipe 14.

The carbid holder 10 is fitted so that its rim 11 surrounds the upperend of the gas washing member '5. Surrounding the upper end of themember 1 and also the carbid receptacle 10,- is the bell 12, whose apronportion fits within the sealing compartment 3 below the water level 4.

It will thus be seen that the gas generated vate, holding thesamebuoyantly as is the usual custom, the outlet for such gas being throughthe pipe 14 and the chamber 7 for the member 5, and the directing pipes13 and 14-. The lower end of the pipe 14 is mounted at 15 through thewall of the mem- -ber'1 and enters the coupling 16,- from which leadsupwardly, the vertical pipe 17, which when the parts are assembled as inFig. 1, is disposed exteriorly of the bell 12 within the casin 2, thepipe 20 being disposed through t e wall of the casing 2 and led to theoutlets (not shown). A valve 18 is connected in the pipe 17 and led fromthe .valve 18 is the union connection 19 so that the parts may bereadily connected and disconnected, and also so that the valve 18'may beclosed to permit of the removal of the condensates as will presentlyappear.

In order to provide a means for receivring the condensates from the gasas it enters thecoupling 16 from the pipe 15, a pipe 21 is connected tothe lower portion of the coupling 16 and has the return member 22connected thereto and to the pipe 23, a smaller 12110824 having its enddisposed within the pipe 23, as clearly illustrated in dotted lines Fig.2, and extended upwardly to a point adjacent to the cover C of themember 2 so that said cap 25 may be removedand a suction pump attachedthereto, to drain the condensate from the pipes 21 and 24c and thereturn member 22. To further safe guard the gas, so that any condensatemay be prevented from entering the outlet pipe 20, a pipe 26 isconnected to the union coupling member 19 at a point adjacent theconnection of the pipe 20 thereto, and such pipe enters the sealingcompartment 3 below the upper surface of the water, so that anycondensate will run down such pipe into the water in the sealingcompartment.

The carbid holder 10, as clearly shown in- Fig. 1, carries the funnelshaped hopper 27 whose outlet end 28 is disposed to be projected toprovide a frusto-conical outlet portion. A tube 29 is disposedconcentrically of the hopper member 27 and has slidably mounted thereinthe rod or stem 30, which carries upon its lower end, the conical valve31, the upper end of the stem being.

provided with the button 32 and the spring 33, said spring normallyholding the valve in seated position, as shown in Fig. 1, and

permitting such valve to be depressed and opened due to the upper end ofthe bell 12 engaging the button 32 asthe bell lowers,

due to the decreasing volume of gas'in the .bell.

As is often the case, upon the automatic return or closure of a valve as31, particles of carbid maybe interposed between the valve and the rimof the member 28. so as to preventthe full closure of the valve, asclearly shown. in Fig. 6, andin order to provide a means to prevent thesifting of the carbid through the space between the valve I and theoutlet 28, a tapered ring 36 controlled by the rod 35 is provided, thisrod' 35 being mr iunted through the tube 34 carried by the carbid holderand as clearly shown in Figs. 1, 5 and 6.

The auxiliary ring or valve 36 is so disposed. as to normally rest uponthe projecting portion of the valve 31, as clearly shown inFig. 1, or itmay be moved through the instrumentality of the lever 38. which isconnected to the upper end of the rod 35 and pivoted upon the stud 37 soas to as sume the position, as shown in Fig. 5, or

flush against the under side of the outle portion of the holder 27.

It will be seen that when the bell 12 lowers, due to the fall of the gaspressure therein, that the under side of the top thereof will engage thebutton 32 and thus lower the valve 31, so that carbid will beprecipitated into the water ofthe generating member 1,-and that thecontinued depression of the bell will engage the upper freeend of thelever 38, so as to move the auxiliary band orring valve 36 to theposition shown in Fig. 5. As the carbid enters the water, acetylene gasbeing generated, the increasing volume thereof will finally elevate thebell 12 and as soon as the top thereof gradually removes pressure uponthe button 32, the spring 33' will gradually move the valve 31 to closedposition, as shown in Fig. 1.. As soon as the cover of the bell hasdisengaged the lever 38, the ring or auxiliary valve member 36 will fallby gravity to assume the position, as shown in Figs. 1 and ('3,therefore should any particle of carbid prc vent the full closure of thevalve 31, it is evident that the ring or band 36 will coact with theValve member 31 to form an auxiliary receptacle for the carbid enteringthe same, thus forming a closure to prevent the continued falling of thecarbid into the generating member 1. It will thus be seen that by adevice of this character, that as soon as the pressure has el vated thebell sufliciently to permit of the proper closure of the valve 31, andsuch valve is hindered from. full closure by the interference of anycarbid particles, that the member 36 will prevent the undue wasting ofthe carbid and the consequent increase and undesirable pres sure of thegas.

In order to provide a means, so that a re served amount of carbid may becarried by .the member 10, thus providing a means "whereby a necessaryamount may be held n reserve, should the volume of gas through the pipe20 be so diminished during the hours of the evening, as to render itnecessary to re-generate, it being impractical then to fill the holder27, a rod 39 is journaled in the member 27 and carries the crank 10exteriorly of the upper end thereof, the portion within the holder 27being provided with the reserve carbid holder 41, 'which rests in theposition to receive a charge of carbid through the aperture 42 closed bythe plug 43. This reserve holder 41 is generally filled when the holder27 is filled, so that it is ready to be emptied at any time it becomesnecessary.

The crank or handle 41 generally assumes the upright position. as shownin Figs. 1

and 7, and is disposed, when the bell 12 is in lowermost position, to bein line to be engaged by either one of the depending aprons d5 of thesupporting member 44, which is connected to and carried by the of thebell 12 through the stopcock 46, so that when the bell is oscillatedthrough the handle 47, either one of the aprons will engage the crank 40and tilt the reserve holder 41 to the dotted line position Fig. 7. Thisaction will empty the reserve carbid into the holder 27, and as thevalve 31 is opened due to the bell resting downwardly upon the button32, the carbid dumped from the reserve holder 41 will pass through theoutlet 28 into the water of the generator member 1. I p The reserveholder 41 is of such a size as to carry suflic-ient carbid to generatesutiicient gas for burning a period of. approximately one night, so thatthe member or hopper 27 may be filled at leisure during the daytime.

From the foregoing description, taken in connection with the drawings,it is evident that with a generator constructed according to the presentinvention, that the water of condensation will be thoroughly removedfrom the gas before the passage thereof through the pipe 20, and that bymeansof the pipe 24, and the cover 25, a suction pump may be connectedto the pipe 24 and thus draw the condensate from the member 22 and thepipes 21 and 23.

By reason of the valve 36, a great disadvantage in a valve controlledfeed is overcome, this particular feature being of the utmostimportance.

What is claimed is:

1. An acetylene gas generator, including a generator tank, a casingsurrounding the generator tank, a bell slidably mounted valve being opendue to the fall above the upper end and around the generator tank, acorbid hopper disposed Within 1 the above the generator tank, a springclosed valve controlling the hopper, said of the bell, auxiliary meansfor preventing the spilling of the carbid from the hopper due to thenon-seating of the valve, said means constituting a frusto-conical ringdisposed concentrically of the outlet of the hopper and in coactiverelation with the valve to provide withithe valve a concentricreceptacle to form with the released carbid a closure between the valveand the hopper.

2. An acetylene gas generator, including a generator tank, a casingsurrounding the generator tank, a bell slidably mounted above the upperend and around the generator tank, a carbid hopper disposed within thebell above the'generator tank, a spring closed valve controlling thehopper, said valve being open dueto the fall of the bell, auxiliarymeans for preventing the spilling of the carbid from the hopper due tothe non-seatin of the valve, said means constituting a rusto-conicalring disposed concentrically of the outlet of the hopper and in coactiverelation with the valve to provide with the valve a concentricreceptacle to form with the released carbida closure between the valveand the hopper, and means connected to the ring and in 006perablerelation to the bell for elevating the ring out of contact with thevalve during the automatic opening of the valve.
